II to support the rounded edges of the glass sheets the es do areslotted es i udiceted set M to so Iva receive the pivot 42 upon whichthe roll 36 is mounted so that the arms may be adjusted and clamped inposition by a nut 43 carried upon the pivot. The arms 34 act to bracethe bracket 26 in the position to which it is adjusted.

Projecting from the end portions 44 of the arms is a series or fingers45 arranged so that each plate of. glass lies between two of suchfingers. The ends of these fingers are provided with rubber caps 46 andthe fingers serve to steady the plates and hold them in position as theymove up and down along the rollers 28, 28 and 30. similarly, another setor fingers 41 are provided at the lower edges of the sheets, suchfingers being secured to the pusher members I I and serving to properlyspace and guide the glass sheets at their lower edges. Mounted on thepusher ll and extending thereirom in the same direction as the arms 3!,is a third series of fingers "a. The fingers "a serve to steady thelower portion of the glass sheets adjacent the edges guided by theroller 31. In order to press the-glass sheets downwardly and give themthe necessary grinding pressure upon the wheels, shot bags 48 are placedupon the sets of sheets, as indicated in Fig. 1. Any other suitablemeans for applying downward Dressln-e to the sheets may be employed andthis pressure may be adjusted to suit requirements.

Fig. 1 illustrates the apparatus adiusted to grind thelower edges of theglass sheets and the rounded corners joining such edges and one of theside edges of each sheet. By a proper adjustment of the runway rollersH, and of the guide brackets 28, each sheet is given the grindingcontact necessary to round the portion of the sheet referred to. As thesheet approaches the first wheel, the portion A (Fig. 3) is engaged bythe wheel. .As the sheet is carried still further forward, the wheelcontacts with the rounded portion B of the sheet, and finally as thesheet rides on of the grinding wheel in its movement to the left, thewheel contacts with the portion C of the sheet. In this manner, thegrinding of a straight surface and a curved surface is accomplished inthe one operation, and during the movement of each'sheet over thewheels, it moves freely in its guide rollers upon the brackets 28 andaccommodates itself to the surface of the wheel. a

Fig. 5 illustrates the adjustment of the apparatus in grinding bodylights 49 having the curved surfaces 50. In this instance, the runway ispositioned somewhat difierently and the brackets 25 instead of being atan angle to the vertical, as is the case in the adjustment of Fig. 1,are placed in a vertical position, so that the glass sheets Id in theirmovement over the grinding wheels move in a right line verticallyinstead of v at an angle to the vertical.

Fig. 6 illustrates the adjustment of the apparatus employed in grindingbody lights having a straight'edge Ii and the rounded corners 52, 53. Inthis instance, the rolls H of the runway sections are adjusted at theangle shown and the brackets 26 occupy the position shown in the figure..As a sheet approaches a wheel, its corner 52 engages the wheel and isground, after which the straight edge 5| passes over the wheel, and asthe plate descends in its movement away from the wheel, the corner It isground. It is thus possible to grind straight or curved edges orpractically any combination of the two,
